ST. PETERSBURG, Fla. -Jarvis Landry wanted to give his home state strong representation. Anthony Chickillo wanted those who watched him to come away thinking he's the country's best defensive linemen. Eli Rogers wanted more respect.

Every player on the Under Armour All-America Game roster had a mission this week at practices in Lake Buena Vista leading up to Wednesday's 7 p.m. contest at Tropicana Field.

Some achieved their goals. Some didn't. But all, it seemed, relished the chance to showcase their talents against players with similar abilities, something they didn't normally get to face at their respective high schools.

"It's a different feeling playing against cornerbacks that are faster than you, bigger than you, stronger than you," said Landry, a four-star receiver from Lutcher, La., who is committed to LSU. "You really had to be on your game."

Tonight's matchup will include many big-name prospects from throughout the country, but none is more heralded than Jadeveon Clowney, a 6-foot-6, 247-pound uncommitted defensive end from Rock Hill, S.C., who is the nation's No. 1-rated prospect.

Suffice to say, Clowney lived up to that billing in practice, utilizing his speed, strength and football IQ to cause havoc to opposing offensive linemen.

"He's a great talent," said Chickillo, a defensive end from Tampa, Fla., and Miami commit who was in the same personnel grouping as Clowney. "He's going to do big things at the college level."

Clowney isn't the only five-star prospect on hand. Offensive tackle La'El Collins, an LSU commit from Baton Rouge, La., who is the No. 2-ranked player, is on the White Team roster and likely will go head to head tonight against Clowney, giving the game the ultimate 1 vs. 2 matchup.

The other five-star players include:

Orlando, Fla., safety Hasean Clinton-Dix, an Alabama commit. At times, he has been a playmaking machine;

Uncommitted offensive tackle Cyrus Kouandjio of Hyattsville, Md., who had the unenviable task of trying to block Clowney on the practice field;

Florida State-bound safety Karlos Williams of Davenport, Fla., who has impressed with his range;

Detroit, Mich., linebacker Lawrence Thomas/db], a Michigan State commit who combines great size with terrific athleticism;

Clemson commit Mike Bellamy, a running back from Punta Gorda, Fla., and possibly the fastest player on hand;

Oklahoma-bound running back Brandon Williams of Brookshire, Texas, arguably the most impressive back this week;

Providing additional drama is the fact several players are expected to announce their commitments during the game, which is being aired on ESPN. Of those who will pledge, Doran Grant is the highest-rated of the group. The Akron, Ohio, defensive back is the country's No. 33 prospect. He will chose between Michigan State and Ohio State.

Practices throughout the week have been competitive, to say the least. But that, quite frankly, is precisely what most of those competing wanted. Simply put, it forced those taking part to raise their game or get left in the dust.

"Everyone out there was trying to show they were the best," Chickillo said. "I love competing and going up against the best. It was fun. I really enjoyed it."

Showing off their respective talents was one goal for most, if not all. Getting better was another.

"I come from a school where there's not too many guys as talented as us," Landry said. "Just being out here with everyone else and seeing the way they play and getting used to that was definitely a good experience."

Some players came to the Under Armour with hype. A few of the ones who didn't arrived with a chip on their shoulders.

"I had a point to prove," Rogers said. "That I was one of the best receivers in the nation."

Off the field, the event gave players a chance to bond, to make new friends.
